摘要/Abstract

摘要：

以69种中国极小种群野生植物为研究对象,结合国际植物物种绝灭风险评价指标体系及评价标准,从濒危野生植物对生存环境适应性的角度,采用层次分析法和调查分析与科学试验相结合的方法,确立中国极小种群野生植物濒危程度评价指标体系,并评估69种濒危野生植物受威胁等级标准。结果表明: 被列为中国极小种群的69种野生植物全部处于濒危状态,Ⅰ级濒危的有2种,Ⅱ级濒危的有35种,Ⅲ级濒危的有13种,Ⅳ级濒危的有19种。

关键词: 极小种群, 野生植物, 濒危程度, 评价指标体系

Abstract:

According to framework of international evaluation index system of plant species extinction risk and evaluation criteria, 69 wild plant species with tiny populations in China were assessed for their endangered levels based on their adaptability to habitat by using the analytic hierarchy process and survey analysis combined with scientific experiments. An evaluation index system was established and with the system all 69 species were evaluated as endangered species, among which 37 species were highest endangered (I level), 13 species higher endangered (II level), and 19 species highly endangered (III level).

Key words: tiny population, wild plants, endangered levels, evaluation index system
